To f//Z/ 'lull/om it 71u07/ concern:

Be it known that I, ARTHUR VILFRnD BRnw'rNALL, a subject of the King of Great Britain, residing at Newcastle-upon-Tyne, in the county of Northumberland, England, have invented certain new and useful Improvements in Surface Heating or Cooling Apparatus, of which the following is a specification.

In surface heating' or cooling apparatus a casing has been employed having four conduits and tubular connections by which two mediums are separately conducted into and out of the casing, passing through a structure contained within the casing in different directions.

The present invention refers to an improved casing of this type to contain any surface heating or coolingstructure constructed with passages extending through from side to side for the passage of one medium alternating with adjacent and separate passages extending through the structure from end to end for the passage of the other medium, so that two of the aforesaid conduits of the casing conduct one'medium to and from the passages extendingfrom side to side of the contained structure, while the other two conduits conduct the other medium to and from the other passages extending from end to end of the contained structure. Broadly, such casings for containing such passaged structures have been heretofore employed; but difficulties have been experienced in removing the passaged structure or structures from the interior of the casing, because to do so it has been necessary to disconnect the tubes or conduits by which the mediums or elements are conducted to or from the casing, although it is highly desirable that such contained structures should be capable of ready removal withouty disconnection of the supply-tubes; and the object of this invention is to provide a construction of casing whereby the contained structure (or structures, where the casing contains several) can be easily removed. A type of passaged structure which the aforesaid casing is particularly designed to contain consists of indented or corrugated plates arranged in surface contact, or nearly so, and fitted or assembled together to form what I will term a bunch and so that between the said plates alternate chambers are formed through which the cooling or heating medium and the medium to be cooled or heated can pass in different directions. rIhe novel and improved construction of such a casing as hereinafter described and claimed is such that a bunch of plates can be bodily removed from the casing without it being necessary to disconnect any of the conduits or tubular connections, or where the casing contains aplurality of bunches of plates all of the said bunches or any particular bunch of plates can be removed also without disconnection of the tubes or conduits by which the elements are conducted to or from the said casing. Such an improved construction of casing is of considerable value and convenience. For instance. in a condenser, say, for marine purposes it is very desirable that when any bunch of plates requires to be removed from its casing Yfor cleaning or repairs it should not be necessary to disconnect the casing from the adjoining parts and connections, and according to this invention the removal of such a bunch of plates can be eectedv without disturbing the connections, and, if so desired, another bunch of plates composing a passaged structure can be substituted by the simple removal of a part of the casing, which can immediately be replaced When another bunch has be/en substituted, and-so permit of practically a continuous working of the apparatus.

The invention will now be described with reference to the example of construction shown in the accompanying drawings, whereori- Figure l is a transverse vertical section of the casing, showing a bunch of plates in position, a portion of the latter being broken away in order to show one of the corrugated or indented plates. Fig. 2 is a similar view, a frame and cover, hereinafter described, having been removed and the bunch of plates shown also partly removed from the casing. Fig. 3 is a sectional side elevation. Fig. I is atransverse vertical section intended to illustrate a frame in the casing which separates the bunches of plates, the example illustrated being a casing intended to contain a plurality of bunches. Fig. 5 is a similar view to Fig. 4C, showing some of the composing parts separated; and Figs. 6 and 7 show, respectively, an elevation and a plan of the apparatusdrawn to a smaller scale than the previous figures.

In such a casing, in which it is necessary to provide four separate conduits, itwill bereadily understood that if such-,conduits whichare to be respectively connected with theinlet and outlet pipes for exhaust-steam and for coolingwater are constructed one immediately upon each side of the'casing, as heretofore, that it is TOO les

then necessary to disconnect at least one of such tubular connections before a bunch of plates could be removed. Now in the construction shown in the accompanying drawings and according to this invention three sides of the casing only are directly occupied by such conduits, the fourth side being fitted with frames and covers, any frame and cover being capable of removal to permit of the withdrawal of a bunch of plates.

Referring to the drawings, 1 is a channelsection side of the casing, forming a conduit extending along one side of the same and formed at its end with atubular connection 2` through which (considering the apparatus as a steam-condenser) the cooling-water is admitted, and the tubular connection 2 is attached to a pipe by which the water is admitted. The water so admitted by the conduit 1 passes through the alternate chambers formed by the corrugated or indented plates and passing out from thence enters a chamber 3 upon the other side,` this chamber being formed by lateral extensions of the upper and lower members of the casing and by a removable end plate 4.

The upper member of the casing forms a conduit 5, Fig. 6, inclined upward from its ends and having a tubular connection 6, Fig. 1, by which exhaust-steam is admitted and passes through the alternate chambers in the bunches of plates, finding its exit by the conduit 8 and tubular connections 7, forming the lower surface of the casing. Both the upper and lower members 5 and 8 are formed with lateral-extending parts 9 10, and skeleton distance-frames 11 are provided, (see particularly Fig. 5,) to which the members 1, 5, and 8 are connected, and these skeleton distancepieces have each a laterally-extending part which takes between the lateral extensions 9 and 10 of the members 5 and 8. Each skeleton frame 11 is formed with a contact-surface 13, and a bunch of plates is slid between two of such distance-pieces, so that its external edges contact with the surface 13.

Upon the side of the conduit 5 forming the upper member of the casing is a passageway 14, and openings 15 are provided in the lateral extension 9 of the conduit 5, by which the cooling-water passes from the ends of the alternate chambers of the plates by the chamber 3 to the passage-way 14, and the passageway 14, as shown at Fig. 7, has a tubular connection 16, which is attached to the pipe by which the cooling-water is taken off.

Referring to Figs. 1, 2, and 3, which show the parts composing the casing assembled, the spaces between the skeleton distance-pieces are each occupied by a rectangular distancepiece 17, which is shown separated at Fig. 5 and n szz/u at Figs. 1 and 3, and the inner face of this frame may be fitted, as shown at Fig. 1, with any suitable packing 18, let into a groove and which contacts with the edges of the bunch of plates, while the said rectangular frame 17 is formed on its outer face 19 with a flange to receive an end cover-plate 4, and the inner surface of the flange 19 contacts with the end surfaces of the lateral extensions 9 and 10 and with the outer edges of the lateral extensions 12 of the skeleton distancepieces 11. Several separate parts, as described, are bolted together in the position shown at Fig. 1. The particular mode of building up an connecting the bunches of plates does not form the subject-matter of this invention; but so far as such bunches are illustrated in the drawings they consistof a number of corrugated plates 20, placed surface to surface, with the corrugations of one plate extending in diverse directions to the corrugations of the next plate. The plain margins of the plates are so arranged that the interspaces at the edges between two plates are closed at the sides and open at the ends, while the interspaces between one of such plates and the next adjacent plate are closed at the ends and open at the sides, and then rigid clampingplates (marked 21 in the drawings) are placed upon each end plate 2O of a bunch and drawn together by bolts 22, and such a construction has been described in the specification of my patent application, Serial No. 255,090, filed Api-i1 12, 1905.

As is suficiently illustrated in the example shown, each bunch of plates 20 is rectangular, and the surfaces of the external end clamping-plates 21 of each bunch which are to contact with the surfaces 13 of the skeleton distance-pieces 11 may be slightly tapered, so that when a bunch of plates is slid into position in the casing a good surface contact with the said distance-pieces 11 will be easily produced.

Obviously those distance pieces or frames (similar to the skeleton distance-pieces 11) which come at the ends of the casing are made solid, so as to form an end closure.

ln the example of construction shown the casing is so placed that the bunches of plates are slid into or withdrawn from the same in a lateral direction, and such is a construction which may suit certain circumstances and particularly when each bunch of plates is of comparatively small size; but it should be understood that when the said bunches of plates are of large size then the cover-plates 4 will be arranged at the top, so that the bunches of plates may be drawn out ina vertical direction, and when so placed and it is required to remove a bunch of plates a coverplate 4 is removed, the rectangular frame 17 immediately beneath the same is drawn out, and the bunch of plates 20 can then be raised from its seatings by means of a crane or other hoisting-tackle.
